Which two subatomic particles are found in the nucleus (center) of an atom?

• A. Protons and electrons
• B. Neutrons and electrons
• C. Protons and neutrons
• D. Electrons and positrons

Answer: (C)

Verified step by step guidance

1. Recall the structure of an atom, which consists of a nucleus at the center and electrons surrounding it in electron clouds or shells.
2. Understand that the nucleus contains particles that contribute most of the atom's mass, while electrons have very little mass and orbit outside the nucleus.
3. Identify the subatomic particles: protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
4. Recognize that protons and neutrons are located inside the nucleus, providing the atom's mass and stability.
5. Conclude that electrons are not found in the nucleus but in the space around it, so the two subatomic particles found in the nucleus are protons and neutrons.
